Automated casting and molding production of submersible centrifugal pump castings

This is a casting factory that provides pump body castings for centrifugal pumping pump manufacturers. The casting factory ordered a conventional horizontal parting automatic casting and shaping machine with a size of 420mm x 520mm sand box in 2017. In 2019, it purchased a horizontal parting automatic shaping machine with a size of 510mm x 610mm sand box again. Two shaping machines were used for the automated casting and shaping production of pump casing castings and pump accessories. The user made and matched a simple wet mold sand treatment equipment to provide molding sand for the shaping machine, which was produced by placing sand molds in the casting workshop;

The casting workshop of this casting enterprise covers an area of about 3500 square meters. Two automated molding machines complete about 900 sand molds in 8 hours a day and are manually placed neatly in the casting workshop. At night, pouring workers melt metal iron and pour all sand molds uniformly. The daily output of castings is about 16T-18T. The sand molds poured at night will be placed and cooled until the next morning, when the workers responsible for molding select the castings. The sand molds after casting are selected and then stacked and watered down by forklifts, and the old sand is mixed again according to the sand requirements of the molding machine;

The submersible water pump accessories produced by the horizontal parting automatic casting molding machine include the casting of the suction port filtration device, made of gray iron casting (HT250), which can reduce the amount of sand and other debris entering the water pump from the suction port.
